iMPRVEMENT IN' LUBRICATING DEVljCES FOR STEAM-ENGINES Specificationl'orming part of Letters Patent rim-190,722, dated May 15, 1877;application'liled.

' I October 3, 1876.

To all, whom t may concern Be it' known that I, WILLiAMMosEs, of thecity of Buialo, in the county of Erie and State of NewYork, haveinvented certain new and useful Improvements in Lubricating De-`vicesfor Steam-Engines, which improvements are fully set forth in thefollowingspecitication, reference being had to the' accompany ingdrawings.

My invention yrelates to a device designed for supplying the lubricatingmaterial to the cylinder or other parts ot' a steam engine, pumporsimilar mechanism, in a regular and uniform manner, while'permitting thequantity of the lubricating material-so supplied to be readilyregulated, as may be required.

The' nature of my invention/Will be fully n n- 'derstood from thefollowing description.

' In the accompanying drawings, consisting of two sheets, Figure l is avertical section of my improved lubricating device. Fig. 2`is a top-plan'view thereof. Fig. 3 is a vertical section at right angles to Fig. 1.FigA is a horiaontal section in line Fig. 3.

Like letters of reference refer to like parts in each of Vthe figures.

A represents the cylindrical oil-receptacle,

` preferably made of glass, and provided with a metallic bottom, A1,adapted to be secured to any suitable support, aud a metallic top orcover, A2, both the top and bottom being prolink, Dl, secured to thecover A2, while the` long arm ofthe lever D is connected by a rbd,

LIP, with any suitable moving part of the engine or pump to which thelubricator is applied, so as to be actuated when the engine or pump isin motion. e is the suction-valve, arranged in a chamber, E,opening-into the receptacle A, and communicating with the footy of thepump-barrel B. j' is the pressurevalve, arrangedin a chamber, F,communicating with the foot of the pump barrel, and

opening into the discharge-pipe Gr, which dives and penetrates thebottom A1 of the oil-receptacle. The pump-barrel B and chambers E and Fare preferably cast in one piece with the bottom A1 ,of theoil-receptacle.

The main portion of the screwed into the bottom of the oil-receptacle,

.is made of any suitable length, as circumstances may require, andprovided near the steam-cylinder, or other part to which the oil is tobe supplied, with a check-valve, g, of any suitable construction.

H represents the return-pipe, connecting with the discharge-pipe G at ashort distance from the oil-receptacle, and opening into the latter, asclearly shown in Figs. 3 and.4. I is a cock or valve, arranged in thereturn-pipe H, for regulating the flow of the oil through thesame. lisan opening formed in the cover A2 for introducing the oil, and L acylindrical strainer, arranged under the opening l, for catching anycoarse impurities which may be contained in the oil.

My improved lubricating device being'connected with a steam-engine orpump, as hereinbefore described, a uniform reciprocating motion isimparted to the plunger C. When the valve I in the returnfpipe H isentirely closed, the full quantity of oil displaced by the plunger Cduring its downward stroke is forced into the cylinder, or other part towhich the dischargepipe G is connected. Upon opening the -valve I to agreater or less extent,l a portion of charge-pipe Gr by the plunger Cisrpermitted to return to the receptacle A by. the pipe H, the amount soreturned being proportionate to the extent to which the valve I has beenopened, and the pressure of the steam opposed to the discharge of theoil from the pipe G. When the valve I is entirely opened all of the oilforced into the discharge-pipe G is returned through the pipe H into there-V ceptacle A. From seen that by opening the valve I to a greater orless extent, the amount of oil discharged from the pipeGr at each strokeof the plunger can be regulaged with great nicety, thus rendering thelubrication regular, and at the saine time adjustable` to the req'enreats ofeach discharge-pipe, y

the oil forced into the disthe foregoing it will bel particular case. Itis evident that motion enay be applied to the plunger U in any desiredand suitable manner.

Having thus fully described my invention, ,'Whait I claim as new, vanddesire to secure by Letters Patent, is y A l. The combination, with theoil-receptacle and discharge-pipe of a lubricatingpump, of .areturn-pipe-provided with a. suitable cock or val-ve for reguieting theamount of oil ejected from the dischergepipe by the action of the pump,substantially as hereinbefore set forth. 2n- 'he combination, with theoil-receptacle A and pump B C, arranged therein, of the discharge-pipe Gand return-pipe H, provided with regulating-valve I, arranged as and forthe purpose hereinbefore set forth.

yEF, the parte being' secured together by bolts a, as and for thepurpose hereinbefore set forth. 4.' The combination, with the oil-vesselA A1 A, of the force-pump B O, discharge-pipe .G, return-pipe H, valvelever D, and actuating rod D2, substantially as and for the purposehereinbefore set forth.
